Yeah, Arcade don't really seem like the type to do a live album, so I won't be too surprised if it is an entire new album. There were reports that they recorded a shit ton of songs during The Suburbs sessions, so maybe they had enough for another album.

i think more bands should try and do this... even though its really ambitious, record a bunch of songs, release one album and then if the material fits and the feeling is right why not release another album? me likey
